The Research of Blasting Dynamices to Slope Rock Mass Damage

Article Preview

Abstract:

The natural slope in the process of excavation, due to the dynamic action of blasting damage the integrity of the original rock, the slope rock mass occurred the partial or whole layer crack and the formation of slope rock mass loose zone, caused the strength of rock mass damage problem, and even lead to landslide. Aiming at the problem of the dynamic influence of blasting on the slope rockmass, study on the algorithm of the blasting damage in this article, combined with the Xiaolongtan coal mine slope engineering as an example to verified the damage model, the results showed that the damage model calculation value and the damage zone measured results have good consistency.
